Blockchain Engineer ‑ Copy-Trade Protocol

Mission:Emit immutable trade clones at the speed of mempools. Engineer on-chain vault + relay contracts that ingest master signals, laser-bridge them across EVM chains, and absorb slippage, MEV, and NFL Sunday-level volatility without exposing followers to liquidation contagion.


Stack & Level Requirements

  • Solidity 0.8.25+ via Foundry toolchain (Forge, Anvil, Cast) or Rust/Anchor on Solana
  • Proficiency: Huff / Yul inlines for gas micro-optimisations, EIP-712 signing, EIP-1167 minimal proxies
  • Cross-layer bridges: LayerZero, Wormhole, CCIP + custom relayers for <2 s finality
  • MEV-Geth style searchers – understand sandwich mechanics to architect commit-reveal patterned entry pools
  • Price oracles: Chainlink CCIP-read, Pyth, custom tick-level fallback for sub-$0.05 deviation error in volatility freak events
  • Security toolkit: Slither, Mythril, Echidna fuzz 1e6 vars/run, invariant bracelets as code
  • Gas profiling: forge-std Vm for on-chain gas snapshots pre-per-release hook


Hard-Check Trader DNA

⚔️ You have personally executed >$10 k notional on perpetuals & on-chain or cross-margined DeFi strategies with stress traces or Etherscan proof of addr.

⚔️ You’ve felt (or caused) impermanent loss >10 % in a single block.

⚔️ Optional but revered: vault or strategy on DeFiLlama/Apeboard with >$50 k TVL linked to your keys.


Responsibilities

  • Build gas-constrained e2e testnets atop Anvil mainnet fork for every release candidate.
  • Continuous white-hat review loop – both formal (Certora specs) & red-team bounty (Immunefi).
  • Coordinate with backend for off-chain signatures (EIP-712 typedData balancers).
  • Draft governance & upgrade timelocks (OpenZeppelin UUPS).
  • Be on-call for on-chain incidents (failed Oracle, stuck bridge, keeper tottering). with protocol parameters YAML files.


Soft Enemies – Don’t apply

  • ifYou only deployed ERC-20 tokens and never** felt liquidation missiles.
  • You ignore MEV game theory.


Perks / Weapons Cache

  • Hardware fund: Apple M Max + 64 GB RAM, 10 Gbps fibre hookup.
  • Personal copy-trading gas allowance 1 k USD monthly – trade openly on testnet, share P&L in public.
  • Health stipend for red-eye debugging—includes premium dark-coffee & builder-milk.
  • Additional 1 % of inflation-scheduled supply upon achieving $100 m copy-AUM on ETH L2.
